Statement 1: A reaction cannot become fast by itself unless a catalyst is added. Statement 2: A catalyst always increases the speed of a reaction.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is TrueCorrect
